METHODS: In focal atrial fibrillation group(65 patients with focal atrial fibrillation proved by radiofrequency catheter ablation) and control group (40 patients with common atrial tachycardia)，the following parameters were measured:total number of single atrial premature beats，number of times and lasting time of atrial fibrillation，number of atrial premature beats which evoked atrial fibrillation or atrial tachycardia and atrial flutter leading to atrial fibrillation， thec ouplingi nterval(P P')，prematurityi ndex( PI)，casesw ithl ongp ause(> 1 .5 s ) ，casesw ith atrialp rematureb igeminyb eforea trialf ibrillation,an dc asesw ithi ntraventriculara berrantc onduction in atrial fibrillation. RESULTS:In focal attrial fibrillation group，there were 497 outbreaks of atrial fibrillation. Atrial fibrillation were all evoked by atrial premature beats which were Von T atrial premature beats. There were significant differences in PP' and PI between atrial fibrillation evoked atrial premature beats and non atrial fibrillation evoked atrial premature beats (PP':spectively. 428士96m sv s519士88m s,P <0.0 5;P I:0. 4 5士0.0 9v s0 .5 5士0.1 2,P <0.0 5)，re-There were intraventricular aberrant conductions accompanied by atrial fibrillation in patients. 5 s) after There were atrial premature beats bigeminal rhythm in 15 patients and long pause(atrial fibrillation ending in 9 patients.paroxysmal atrial tachycardia in all patients byIn the control group，there were common short dynamic electocardiogram analysis，and there were significant differences in PP' of atrial tachycardia or atrial fibrillation evoked premature beats and PI，respectively.
